The First Law of Thermodynamics, known as Conservation of Energy, states that when energy is transformed, the total stays the same. Describe TWO examples of the first law, one involving living organisms and one not involving living organisms.

Given the bond enthalpies C=O (707), O=O (498), H—O (464), and C—H (414) in kJ/mol, compute Δ H° in kJ/mol for: CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g)     +259     -618     -259     -519     +618

Given that the reaction N2(g) + 2 O2(g) → 2 NO2(g) is endothermic, what is true of the reaction 2 NO2(g) → 2 N2(g) + 2 O2(g) ?
